Which statement best describes how electrons fill orbitals in the periodic table?

We are asked to describe how electrons fill orbitals in the periodic table. Among these, the correct statement is that electrons fill orbitals in order of increasing energy from left to right. This is verified by Aufbau principle. We see that as we move across from left to right, as the group number increase, the number of valence electron/s of each group also increases.

Answer: The statement that best describes how electrons fill orbitals in the periodic table is "Electrons fill orbitals in order of their increasing energy from left to right". It's possible to see this effect once we notice that, from left to right, the number of electrons related to each atom increases, showing that the orbitals are being filled according to Aufbau procedure.

What volume of nitrogen (n2) would be completely consumed in the reaction with 30.80 g of
Shtirlitz [24]

The answer is 285.33g nitrogen would be completely consumed in the reaction with 30.80 g of hydrogen gas.

<h3>What is a mole ?</h3>

A mole is defined as 6.02214076 × 10²³ atoms, molecules, ions, or other chemical units.

Write a balanced equation.

Calculate the moles of H₂ in 30.8 g.

Calculate the moles of N₂ required to react with H₂.

Calculate the mass of N₂.

Calculate the initial mass of N₂.

Start with a balanced equation.

N₂ + 3H₂ --> 2NH₃

Calculate the moles of H₂ in 30.8 g.

n = m/M; where n = moles, m = mass, and M = molar mass.

M(H₂) = 1.008 g/mol

n(H₂) = (30.8 g)/(1.008 g/mol) = 30.56 mol H₂

Calculate the moles of N₂ required to react with 30.56 mol H₂ , using the mole ratio between H₂ and N₂ in the balanced equation.

30.56 mol H₂ × 1 mol N₂/3 mol H₂ = 10.18 mol N₂

Calculate the mass of N₂ in 10.18 mol.

m = n × M

M(N₂) = 2 × 14.007 g/mol N = 28.014 g/mol N₂

m(N₂) = 10.18 mol × 28.014 g/mol = 285.33g N₂

Therefore 285.33g nitrogen would be completely consumed in the reaction with 30.80 g of hydrogen gas.

Two ways friction is harmful when riding a bike
Nat2105 [25]
If your bike isn't the right size, your legs could be rubbing up against the seat of your bike. The friction can chafe the skin on your legs. If you were to crash your bike, skidding on the ground can cause anywhere from minor scrapes to serious friction burns.

A gas at a pressure of 2.0 atm is in a closed container. Indicate the changes (if any) in its volume when the pressure undergoes
garik1379 [7]

Answer:

a) The volume increases

b) The volume decreases

c) The volume does not change

Explanation:

<em>A gas at a pressure of 2.0 atm is in a closed container. Indicate the changes (if any) in its volume when the pressure undergoes the following changes at constant temperature and constant amount of gas.</em>

<em />

When there is a change in the pressure (P) at constant temperature (T) and amount of gas (n), we can find the change in the volume (V) using Boyle's law.

P₁.V₁ = P₂.V₂

where,

1 refer to the initial state

2 refer to the final state

<em>a) The pressure drops to 0.40 atm.</em>

P₁.V₁ = P₂.V₂

(2.0 atm) . V₁ = (0.40 atm) . V₂

V₂ = 5 . V₁

The volume increases.

<em>b) The pressure increases to 6.0 atm.</em>

P₁.V₁ = P₂.V₂

(2.0 atm) . V₁ = (6.0 atm) . V₂

V₂ = 0.33 . V₁

The volume decreases.

<em>c) The pressure remains at 2.0 atm.</em>

P₁.V₁ = P₂.V₂

(2.0 atm) . V₁ = (2.0 atm) . V₂

V₂ = V₁

The volume does not change.
